[news.eclipse.platform.swt] activeEditorPart is always null (setActivePa

[David Black <dblack@xxxxxxxxxxxxxxx>]

Hi,

I have a MultiPageEditorActionBarContributor and a multi page editor 
with 2 pages. Every time 
MultiPageEditorActionBarContributor.setActivePage is called, the editor 
part passed to it is null. Each time I click on the tab of one of 
editors, setActivePage is called but with null. I have tried calling 
setActivePage(0) and setActivePage(1) and both times the same thing, 
null. I traced the code and there is a CTabFolder involved for the 
mutlipage editor, and the lookup of the CTabItem takes place, but its 
data property is null. Should the CTabItem data property point to my editor?

Is there an "obvious" reason for this? Something I have forgotten to do 
perhaps ... my multiple editors work fine apart from this. Problem is I 
have nowhere to direct my actions from the contributor if I cannot 
access the activeEditorPart.

thanks
